From my blog:http://blog.trailcooking.com/2012/08/01/new-recipe-sunflower-honey-balls/

Easy to make, raw friendly and both kids and adults will love them. If you don’t like Medjool dates (and I’ll note that until I tried Medjools I hated dates, they are so different!), feel free to use organic raisins or prunes instead (D’Noir™ are great).

Add the sunflower seeds and dates to a food processor, run on high until small pieces. Add the remaining ingredients, process on high until a ball forms. Line a small baking sheet with parchment or wax paper and make 1 Tablespoon balls, rolling in your hands to smooth. A 1 Tablespoon Disher works nicely. Chill in the refrigerator, then transfer to an airtight container.

We tried the Medjool dates (got them at Whole Foods) and they are good if eaten by themselves. We have bought different brands of dates from Publix, Whole Foods and Costco (don't sell Medjool). IMO when mixing them with everything else you can't tell any difference between the dates.

Your Costco doesn't carry them? That blows! The Medjools they carry out here are some of the best I have seen - very plump, large and fresh. Where as the Trader Joe ones tend to be smaller and harder. I was nearly tuned off dates as a kid, due to my well meaning Nana, who would serve them to us. Except hers were rock hard and of questionable variety ;-) They were so gross. Thankfully I gave them a try again!
